Flowers aren’t just for saying “I’m sorry.” They can also improve your sex life. Flowers are natural sources of aromatherapy – scents that communicate with receptors in the brain to affect emotion, cognition and even physical arousal.

So which bloom should you choose? Roses are especially great for your love life. They contain the chemical compound phenylethylamine (PEA), a natural substance that stimulates sexy, mood-altering feelings. According to sex researcher Helen Fisher, Ph.D., author of Why We Love (Owl Books, 2004), PEA gushes out of the brain when we fall in love. It’s a part of a powerful chemical cocktail that happens during early infatuation with a new partner that makes us, well, like each other so much!

If you want to recapture that feeling of puppy love with your honey, keep a vase of roses next to your bed for a natural high.

Flowers are a fat-free, no-guilt way to spice up your love life. But guess what else contains PEA? Chocolate. Seems the old chocolate and roses combo are the perfect romantic gift after all.
